The beautiful and fascinating gemstones, diamonds are naturally occurring stones that undergo exposure to extreme heat and temperature conditions under the crust of the Earth. Even though diamonds are available in the market in a wide variety of colors, fancy colored diamonds are extremely rare when compared to colorless diamonds.

Most of the fancy colored diamonds available in the market are usually discovered from the mines of Brazil, Australia, and Africa. The rarest and most valuable type of fancy colored diamond available out there is undoubtedly the red diamond. Reports from several reliable sources claim that just twenty to thirty red colored diamonds are known to exist and the carat size of most of these stones was less than half.

As you would probably, the color of fancy colored diamonds is due to the presence of impurities within them, which get in the stone at the time of their formation process. However, the distinct color of red diamonds is not due to the presence of any impurities; instead, it is due to a very rare occurrence in the atomic structure of red diamonds.

Another interesting thing you should know about red diamonds is that they have the unique ability to appear differently colored when viewed under different lighting environments. Red diamonds look elegant and beautiful in candlelight and daylight, whereas they look worst when they are placed under fluorescent light. Regardless, some of the world-famous red diamonds that were mined from the crust of the Earth are as follows.
